Master Yi Alpha is broken once again.

So after playing yi in a game, this bug accured 3 or 2 times, i alpha a champion but when i leave i get teleported to the wrong champion. for example i alphad the karma but got teleported on wukong. This completely fuked me up, as i cant get a kill and reset. The other time was when i alpha on mf but teleport to chogath. Rito plz fix it, although i think yi's alpha is probably the hardest ability to code in the game.
